Eco system services model on Mount Gede Pangrango National Park based on carbon stock and plant diversity 42 v EXECUTIVE SUMMARY Mount Gede Pangrango National Park (MGPNP) is a wet-climate mount ecosystem that is rich for its plant diversity and has a significant contribution in storing carbon stock in its biomass and in time, it should be an ecosystem service. The purpose of this research is (1) to obtain information and data of carbon stock in relation to the plant diversity on nature forest ecosystem of Mount Gede Pangrango National Park as the core zone of Cibodas Biosphere Reserve (2) to formulate ecosystem services model on the wet climate mountains in West Java based on the strong linkage between carbon stock and plant diversity, and (3) to support scientific data in welcoming REDD/REDD plus, thus the result will directly contribute to the multistakeholder in Cibodas Biosphere Reserve for participating in reserving the main site. The method of measurement consists of (1) dividing Mount Gede Pangrango National Park in its each unique ecosystem as follows: (a) submontane zone (1000-1500 m asl), (b) montane zone (1500-2400 m asl), and (c) subalpine zone (2400-3019 m asl); (2) measuring the carbon stock above and below ground by using World Agroforestry Center (2007) as a guide; (3) estimating the biomass of branched trees by applying the equation of Dry Weight/DW as follows: (a) DW = 0,118 D2,53(Brown, 1997), (b) DW = 0,11 ρ D2,62 (Ketterings et al., 2001), (c) AGB est= ρ x exp(-1,499 + 2,148ln(D) + 0,207(ln(D))2-0,0281(ln(D))3) (Chave et al., 2005), (d) Ln (TAGB) = c + αln(DBH) (Basuki et al., 2009). The estimation of the biomass of non-branched trees uses DW = π ρ HD2/40 (Hairiah et al., 2001); (4) calculating plant diversity by using quantitative parameter, including index of importance value, index of diversity and index of similarity; (5) analyzing the relationship between carbon stock and plant diversity by using excel program on Mac OS X Version 10.5.8 and model test of polynomial regression on the confidence level of 95%; and (6) calculating of carbon value based on the ecological zone ability in supporting carbon. The average result of carbon stock measurement (aboveground carbon stock) on 9 sites using four allometric equations in tons C per hectare is 399.717 (Brown/Br), 354.648 (Ketterings/Kt), 449.688 (Chave/Cv) and 325.724 (Basuki/Bs). The estimated biomass is assumed that its 46% is stored carbon stock which is as much as 868.950 (Br), 770.974 (Kt), 977.583 (Cv) and 708.095 (Bs). The highest carbon stock is found on 2329 m asl (montane zone), except Bs allometric on 2601 m asl (subalpine zone), and the lowest one is found on 1355 m asl (Br) and 1079 m asl (Kt, Cv, Bs). The average of highest carbon stock based on zone is on the subalpine zone, that is 409.751 (Kt), 553.858 (Cv), vi 411.661(Bs) except Br (463.466) on the montane zone. It is presumably caused by contribution of Vaccinium varingiaefolium, which is multistem as well as dominant species on the subalpine zone. The maximum proximity value from the big trees to the small ones happens on the subalpine zone, that is 280 individuals ha-1 of the big tree (2601 m asl) and 2950 individuals ha-1 (2802 m asl). Meanwhile the approximate average of contribution on the aboveground carbon stock from the big trees 42.697-51.963% and from the small trees 29.664-35.892%.

    Advances in Social Science, Education and Humanities Research, volume 570 Proceedings of the International Conference on Economics, Business, Social, and Humanities (ICEBSH 2021) Creative Strategy to Reduce Littering for Hikers Christian Chandra1 Anny Valentina1* Siti Nurannisa1 1Faculty of Art and Design, Universitas Tarumanagara, Jakarta, Indonesia *Corresponding Author. Email: [email protected] ABSTRACT Since a drastic increase of mountain national park visitors, the littering problems were emerging more than ever. Many hikers, especially the amateurs, keep ignoring the park’s rules about littering. Many sanctions be it from national park itself and nature lovers community has been deployed, yet the problems still occurs until now. This research has found a gap between these solutions to mountain’s litter problem. The lack of education to prevent hikers from littering is actually, needed. Not just cleaning the existing litters. This research was conducted using descriptive qualitative methods, to acquire data such as interview with the personas, questionnaire, and observation. The results of the study show that many hikers already know of the banning of littering in the mountain, but they didn’t know how to prevent that, ironically those littering behaviors related from the methods they use since they packed their apparels. Creative strategy is used as the framework of this comprehensive method. The author adopted a set of simulation process named 5A (Aware, Appeal, Ask, Act, Advocate). This method helped author to place each visual communication in the right time, places and ways, matching with the researches and findings. Keywords: hiking, littering, mountain, campaign, creative strategy 1.

Here, we report on activities, habitat use and diet of Trachypithecus obscurus in a human-impacted landscape in Penang Island. We studied the relationship of these primates with their habitat to facilitate conservation management plans. We used group scan sampling to assess activity budgets and recorded home range size, stratum use and food plant species and parts. The home range of the study group was 12.9 hectares, including secondary forest (61.2%), a nature park (23.9%) and beach (14.9%). Langurs mainly rested (43.5%) and fed (24.8%) and spent significantly more time resting and foraging in the secondary forest than elsewhere. They mainly fed on leaves (60.3%) and consumed 56 identified plant species from 32 families of wild and cultivated plants. Langurs behaved differently and ate different plant species in different habitat types and the group had to cross a busy motorway to reach the beach, thus, we also report on road crossing behaviour. These langurs have seemingly adapted well to disturbed habitat however, more comparative studies are needed to predict long-term effects of habitat degradation on the population of this species and to develop feasible conservation plans.

  • Detailed Final Report
    An urgent conservation call from endemic plants of Mount Salak, West Java, Indonesia I Robiansyah* and S U Rakhmawati Research Center for Plant Conservation and Botanic Gardens - LIPI. Jl.Ir.H. Juanda 13 Bogor 16003, West Java, Indonesia *[email protected] Abstract. Mount Salak is part of Mount Halimun-Salak National Park in West Java, Indonesia. It is home to five endemic plant species that are very susceptible to human interference due to their close proximity to human settlements. The deforestation rate of the area was 1,473 ha or 1.3% of the total area each year. Using eleven line transects with a total length of 44.76 km, the present study aims at providing data on current population and conservation status of these five endemic plant species. The results showed that there was an urgent conservation call from Mount Salak as all five targeted species were unable to be located. Furthermore, two invasive species that might possess serious threat to the endemic plants were observed during the survey: markisa (Passiflora sp.; Passifloraceae) and harendong bulu (Clidemia hirta; Melastomataceae). Based on these results, the present study assigned all the endemic species as Critically Endangered according to the IUCN Red List Category and Criteria. To conserve all the endemic plant species in Mount Salak, several recommendations were given and discussed. 1. Introduction Plants are fundamental part of terrestrial ecosystem and provide support systems for life on earth. For human, plants provide many essential services that underpin human survival and well-being, such as source of food, clothes, timber, medicines, fresh air, clean water, and much more.

Revision accepted: 30 June 2009. ABSTRACT Junaedi DI, Mutaqien Z (2010) Diversity of tree communities in Mount Patuha region, West Java. Biodiversitas 11: 75-81. Tree vegetation analysis was conducted in three locations of Mount Patuha region, i.e. Cimanggu Recreational Park, Mount Masigit Protected Forest, and Patengan Natural Reserve. Similarity of tree communities in those three areas was analyzed. Quadrant method was used to collect vegetation data. Morisita Similarity index was applied to measure the similarity of tree communities within three areas. The three areas were dominated by Castanopsis javanica A. DC., Lithocarpus pallidus (Blume) Rehder and Schima wallichii Choisy. The similarity tree communities were concluded from relatively high value of Similarity Index between three areas. Cimanggu RP, Mount Masigit and Patengan NR had high diversity of tree species. The existence of the forest in those three areas was needed to be sustained. The tree communities data was useful for further considerations of conservation area management around Mount Patuha. Key words: Mount Patuha, tree communities, plant ecology, remnant forest. INTRODUCTION stated that the conservation status of tropical mountain rainforests of West Java has reached threatened conditions.

The genus is described and its distinguishing features and apparent relationships are discussed. The six species are keyed, described, and their apparent relationships are outlined. New combinations are made for the names of three species, Maclurodendron porteri, M obovatum, and M oligophlebium, all of which were previously described in the rutaceous genus Acronychia, and three species, M pubescens, M. par· viflorum, and M magnificum, are described as new. Introduction Among the previously described species excluded from Acronychia J. R. & G. Forst. in my revision of that genus (1974) are A. porteri Hook. f., described from W. Malaysia, A. obovata Merr., from the Philippines, and A. oligophlebia Merr., from Hainan Island. These three species plus three others that are undescribed, one from W. Malaysia and two from E. Malaysia, comprise a morphologically isolated group of plants that has not been previously recognised. The purpose of this paper is to give a taxonomic account of this group, which is here described as a new genus. Geographically, these plants range from Sumatra and the Malay Peninsula east to the Philippines and north to Vietnam and Hainan Island (Fig. 1). To Acronychia, which ranges from India to southwestern China and throughout Malesia to eastern Australia and New Caledonia, they are similar in a number of characters, including their opposite leaves, 4-merous flowers, biovulate carpels, and syncarpous, drupaceous fruits.
